The
Cat Ba langur
(Trachypithecus
poliocephalus poliocephalus), also known as Golden-headed langur, is
endemic to the
island of Cat Ba in Northern Vietnam. By the year 2000, poaching had reduced
this species to only fifty or so individuals in several
isolated
sub-populations. It was then that the Cat Ba langur was listed by
the World Conservation
Union (IUCN), as one of the world’s
most endangered primate species.

Towards the end of 2000, Münster Zoo and the
Zoological Society for the Conservation of
Species and Populations (ZGAP) formed
a cooperative partnership
with Vietnamese conservation agencies, and the “Cat Ba Langur
Conservation Project” was initiated. Since
then, langur poaching has been brought
under control.
